Has anyone tried this with warm/cold water? I always wash all my clothes in cold water and only put them in the dryer for ~10 minutes before hang drying, so I'm pretty worried about the shrinkage that might happen with hot water.

Damn. Thanks for the explanation. I will have to figure something out re: the MOP buttons.
Still, this method dominates stains.

I'm not sure where I saw it, but I read on this site that using any kind of oil on MOP buttons that were dulled by the vinegar would help. I tried it out and indeed it does bring the buttons back to their original luster, and make them incredibly smooth. I used grape seed oil, but I'm sure most others will work. Just be careful about not getting any on the (white) shirt. I just put some oil on the tip of my finger and lightly "dab" each button face and let it absorb.

I used Oxyclean recently and it worked fantastically. I sprayed on stain remover, brushed the fabric a bit and let the shirt soak overnight. From there I put the shirt in the washer and it came out completely like new... I was pretty surprised.

Can't speak to that product, but I can tell you that Shout Advanced Gel gets rid of ring around the collar brilliantly -- no oxy anything required, and therefore retaining the luster on your MOP buttons. You have to use the fabric brush at the top of the bottle to really work the stuff into the stain.

(I do use the Spray N Wash spray for non-ring-around-the-collar stains and it's great.)

I have a question with the Oxy-Clean method (esp. to Versaceman). There is no available Oxy-Clean powder (the one in a tub) in the nearest supermarket, but there's an Oxy-Clean stain fighter in liquid. Is this an acceptable substitute? If I'm going to use it, do I have to the change the amounts, etc.? Thanks in advance.

Haha, J, I'll type it up for ya: Step 1: Soak shirt in a solution made from one gallon hot water (as hot as it will come out of the faucet) and one cup of vinegar. Let the shirt soak for 30 mins to 2 hours. Step 2: Rinse shirts, and squeeze out excess water. Empty bucket and rinse. In a cup, prepare a concentrated Oxy-Clean solution. Make sure to use the Oxy-Clean granules that come in the tub. Make the solution about 10 parts HOT water to one part O-C. Usually this amounts to two scoops of O-C (using the provided scoop) per 4-6 ounces of water. You want this to be very concentrated. Step 3: Apply the strong solution generously to the stained areas. Place the shirts in a bucket (so that the solution doesn't flow away, or dry) with the stained areas towards the bottom of the bucket so they stay nice and covered in the solution. Allow to soak overnight. It can also help to use an old toothbrush and scrub the stained areas every hour or so, if you've got the time. Step 4: In the morning, remove the shirts from bucket. Fill the bucket with a gallon of hot water, and two scoops of the Oxy-Clean (basically, follow the recipe on the package for a general cleaning solution) and mix well. Place the shirts in the bucket, and soak for 2-24 hours. This just helps to remove any trace of stain. You might want to stir the shirts around with your hands after you put them in the bucket with the weaker solution just to remove some of the stronger solution that is still on the shirts. Step 5: Remove, and wash/rinse in the regular cycle on your washing machine. Note: I find that this normally removes sweat/dirt stains from the armpit, neck, and cuff with ease. For really strong stains, you might have to repeat the process a few times. However, with this, I've been able to remove some major sweat stains that have been set into shirts for five years, at least.

call me an idiot but whats an example of the concentrated solution? I feel if i put 2 scoops of the OC in 12 oz of hot water it would be like paste. How could you soak a shirt in this??

If you use hot water as it recommends, you will get a liquid solution. If you are using a paste-like solution, you will not get the benefits of the relatively simple chemical compounds in oxiclean. i used this method yesterday 2 scoops + 16 fl oz of hot water, it came out a liquid, I assure you. Worked like gangbusters on some 2 year old ring-around-the collar and cuff stains.
